Abstract: In the emerging high-speed rail hub city of Shang-rao City as the research object, with the ARCGIS software and using a grid analysis method to study Shang-rao City reachability Pattern Change, the reachability pattern is divided into high-speed rail has not been opened before and become high-speed rail hub faces two time periods, and then found that the pattern of evolution of Shang-rao City reachability obviously has the following four characteristics: (1)Up to a very significant improvement(2) Accessibility direction substantially expand "cross" distribution(3) Accessibility improved significantly focused on "Yangtze River Delta" and "Western Taiwan Straits Economic Zone",(4) Also affected by road transport from road and air transport. Based Shang-rao City, accessibility and spatial evolution of the characteristics, this article also presents response strategies and recommendations after Shang-rao City becoming the emerging high-speed rail hub of the city and how to take advantage of this superior traffic advantages to seek their own rapid development, We got to look forward to providing guidance to the rise of Shangrao City.
